Since second-to-fourth digit ratio (2D:4D) measures might afford a window into the prenatal environment in terms of testosterone exposure, many researchers are focused to find out the relations between sexually dimorphic characteristics and 2D:4D. Aim of this study is to find out whether there is a relation between sexually dimorphic subcutaneous fat distribution and 2D:4D. Height, weight and skinfold thickness (SFT) were measured in 120 male and120 female university students. Trunk SFT (sum of subscapular and supraspinale) and limb SFT (sum of triceps, biceps and calf) was used as the absolute amount of the trunk and limb fat, respectively. Limb / trunk fat ratio were used as the indices for therelative distribution of fat mass in the trunk and limbs. The length of index and ring fingers of the participants was measured to the nearest 0.01 mm using Vernier caliper, directly on fingers.As a result correspondingly to the feminine 2D:4D in both hands of men and in the right hand for women; body fat distribution gets feminine. There was no relationship between total fatness and 2D:4D for either sex. These findings could mean that sexually dimorphic body fat distribution is closely related not only to postnatal but also to prenatal steroid levels.
